I created an order guide and it processed 3 catalog items in parallel. The sequential fulfillment plug-in was recently installed. I then took that same order guide and selected generate sequence. I am now getting the playbook error Invalid Reference for each of the 3 catalog items. When I click on the link to the catalog items and go to the Automation tab, there is a field labeled "Request" that contains the "Invalid reference". What is causing the Invalid Reference error? Is Request referencing a field on the parent record?
